Eyes and ocelli reddish (in preserved specimens). Fore and middle legs yellow except coxae and claws brown; hind legs yellow except coxae, distal 3/4 of femora, distal 3/4 of tibiae and tarsomeres brown. Petiole on T1 brown and sublateral areas yellow-brown; T2 with median area brown, and adjacent area and lateral ends yellow-brown; T3 and beyond brown; distally each tergum with a narrow whitish transparent band. In lateral view, T1-3 yellow-brown; T4 and beyond brown. S1-3 yellow-brown; S4 and beyond brown; ovipositor sheaths brown.

Description.

Head ( Fig. 56A, B, E View Figure 56 ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.17:0.05, 0.18:0.05, 0.18:0.05), distal antennal flagellomere longer than penultimate (0.12:0.05, 0.8:0.05), antenna longer than body (2.63, 2.02); antennal scrobes-frons shallow. Face with scattered finely punctate, interspaces wavy, distal half dented laterally, and longitudinal median carina present. Frons punctate. Temple wide, punctate and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 0.12). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 56 A–C, E View Figure 56 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally ranging to satiny distally and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum completely concealed; BS only very partially overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular and bisected by a median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved with medium-sized sculpture and distal half with fine sculpture; distal edge with a flange at each side and without stubs; propodeal spiracle without distal carina; nucha surrounded by very short radiating carinae. Pronotum virtually without trace of dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine punctations throughout and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep faintly lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs. Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.20, 0.15), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.11, 0.09).

Wings ( Fig. 56I, J View Figure 56 ). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming an angle at their junction and outer side of junction forming a slight stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell proximal half smooth; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe wide, subdistally and subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 56A, D, F–H View Figure 56 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 and apex truncate (length 0.29, maximum width 0.14, minimum width 0.10), petiole with little pubescence on distal half. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.10, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.15, minimum width 0.06); T2 with scattered pubescence throughout. T3 longer than T2 (0.20, 0.15) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. Beige or gray-white oval cocoons with silk fibers evenly smooth. Cocoons forming two parallel rows of cordwood with the caterpillar in the middle.

Comments.

The specimens are slim.

Male

( Fig. 57 A–J View Figure 57 ). Similar in shape and coloration to the female.

Etymology.

Christer Hansson is the curator Museum of Zoology, faculty of Science at Lund University, Sweden. He is interested in some Chalcidoidea  families.

Distribution.

The parasitized caterpillars were collected in Costa Rica, ACG, Sector El Hacha (Finca Araya and Sendero Tigre), during July 1999 and October-November 2001 at 280 m and 295 m.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Lepidodes gallopavo   Druce ( Noctuidae   : Catocalinae  ) feeding on Bunchosia polystachia   ( Malpighiaceae  ). Caterpillars were collected in fourth and fifth instar.
